Far infrared rays widely exist in nature, have strong permeability and radiation capacity, have obvious temperature control effect and resonance effect, are easily absorbed by an object and are converted into internal energy of the object, and the conversion of the internal energy and the internal energy of the object is usually accompanied with the heat effect. The far infrared heating body material is an application material which effectively utilizes far infrared rays, is various, mostly adopts carbon crystal, short carbon fiber and an electrothermal film, but the products are limited by self conditions, cannot simplify the whole structure, cannot ensure the use safety and high thermal efficiency, and limits the whole use environment and field of the heating body material.
In recent years, some prior arts have proposed solutions to the above-mentioned problems for heat-generating body materials. The wire-bound heating element uses fiber fabrics as a flexible bearing substrate, the carbon fiber or metal fiber heating element is fixed on the bearing substrate in a sewing or gluing mode, and a sandwich structure of one layer of heating element is sandwiched between two layers of flexible substrates, but the heating element has larger thickness and hard texture, small heating area occupation ratio and is not resistant to bending; the conductive ink heating body uses polyester plastic films such as PET and PI films as flexible bearing substrates, carbon-containing conductive ink is attached to the bearing substrates in printing and other modes, and a sandwich structure of a heating body is sandwiched between two layers of flexible substrates to form an electric heating sheet. The solutions of the heating bodies have a similar industrial common fault, namely when the heating bodies are used for fiber products or intelligent wearing articles, the power consumption capacity of the mobile power supply is limited, so that the corresponding size of the electric heating sheet is difficult to manufacture a large-area heating system, the product quality of the corresponding product is reduced, and the production economic cost of the product is obviously increased.
The prior art (CN201510635047) provides a preparation method of a graphene heating element, a graphene heating element material is prepared by preparing a film-forming resin solution and simply mixing and coating graphene, and is claimed to have excellent heat conductivity and electrical conductivity, but the dispersion of a single-dimensional material in a resin is very easy to generate the conditions of population aggregation and poor dispersion of the graphene material, which greatly limits the heat conductivity and heat conductivity uniformity of the heating element material, and reduces the service performance of a heat conducting material.
Therefore, there is a need for a composite exothermic body material which has a moderate thickness, a soft texture, a high proportion of heat generating area, a flexible folding property, and a waterproof property, and can be washed, so as to expand the application environment and field of the exothermic body material, such as the textile field.
According to the invention, the composite resin heating element material which has excellent heating area ratio and can resist folding and bending is prepared by reasonably proportioning the multiple heat-conducting carbon materials and the thermoplastic resin, and the technical problems of small heating area and the like in the prior art are fully solved.
